Tia ‘knew right away’ Tamera was pregnant

It didn’t take long for Tia Mowry-Hardrict to guess that her twin sister, Tamera Mowry-Housley, was pregnant.

“I knew right away,” said Tia, who is the mother of a 10-month-old. “I guessed it. She didn’t tell me. I had to ask her.”

Although some twins claim to have a psychic connection, Tia simply used her powers of deductive reasoning to figure out that her sister was in a family way.

Tia’s first clue was that Tamera, who she described as a "wino," didn’t order a glass of wine when the two had dinner together. Then, Tia became more suspicious when Tamera decided not to go snow tubing.

However, those weren’t the big signs.

“The thing that really got me… she threw up in the car,” Tia explained to Wendy Williams.

While Tia talked about the pregnancy surprises that caught her off-guard—like an increased sex drive—Tamera will have the benefit of her sister’s experience.

Tia’s book, Oh, Baby!, which offers pregnancy advice, is now available in stores.

“I just wanted to share with all of the expecting moms out there, what it’s like basically being pregnant,” Tia said in a Penguin Publishing video. “I think the main reason why I wanted to write this book is because I wanted it to be a great experience and a fun experience because being pregnant can be scary.”

Although the book shares lots about the physical changes a woman experiences while with child, Tia said she also talks about style and learning to balance career with motherhood, something her fans will see when “Tia & Tamera” premieres in June.

“My favorite chapter in the book would definitely have to be the ‘Hot Mama Style’ chapter," she said. “I talk about cool shoes that you can buy or wear that look great on pregnant women. Usually you’re always talking about wearing black to slim your figure, but it’s okay to wear color and embrace that belly ‘cause that’s what makes a pregnant woman so sexy.”
